poly[(2-methoxy,5-octoxy)1,4- phenylenevinylene-carbon nanotube composites (MOPPV-CNTs) were synthetized by In-situ polymerization in the paper. The molecular structure and surface morphology of the nanocomposites were characterized by the TEM. The TEM results showed that the MOPPV coated on the CNTs forming Core-shell nanowires structure composite. The wavelength of UV-absorption spectra of the composites exhibited a blue shift caused by the functionalized MWCNTs. the energy gap of the composites were increased. The band structures of the composite were determined by using cyclic voltammetry, the result shown that the HOMO energy and the LUMO energy increased with the concentration of CNTS. The increase of LUMO energy would benefit for balance of the carries injection when the composites used in the optoelectronic devices.

Carbon Nanotube Composites

Ternary composites of Ag–loaded polypyrrole/carbon nanotube (Ag–PPy/CNT) are prepared using a one–step in situ polymerization. Ag nanoparticles are uniformly decorated on the core–shell PPy/CNT networks. This approach provides a simple, easily accessible strategy for preparing three–dimensional noble metal–conductive polymer–carbon nanotube composites. Electrochemical properties of Ag–loaded composites are evaluated to understand the effect of Ag on the structure and kinetic process of the composite. Results indicate that the composites have good electrochemical reversibility and high specific capacitance. The specific capacitiance of Ag–PPy/CNT composites are enhanced greatly from 206.7 F g–1 of PPy/CNT composites to 528.6 F g–1 at 3 mA cm–2. This demonstrates that combining nano–sized Ag with supercapacitor materials is very effective in promoting electrochemical performance of materials.
